2:41pm: The Diamondbacks have agreed to terms with supplemental first round pick Andrew Chafin, tweets Baseball America's Jim Callis. The D'Backs selected Chafin, a left-hander out of Kent State, 43rd overall as compensation for losing Type B free agent Adam LaRoche. Terms of the deal are not yet available.

Chafin, who missed the 2010 season due to Tommy John surgery, was ranked 38th by Baseball America heading into the draft. The 6'2", 210-pound southpaw throws his fastball comfortably in the low 90s but can touch 95 with his heater. He has drawn praise for his wipeout slider, which some scouts rank as a 70 on the 20-80 scale.

ESPN's Keith Law (Insider required) had this to say about Chafin at the time of the draft:

"At worst Chafin's an interesting pen arm because he's left-handed with good velocity, but he has the body and delivery to start if his off-speed pitches improve."
